SQL to omit value if a match - sql-server-2008

The following field of a table:
AttorneyEmail(varchar(150), null)
Can have more than one email address, but has this email address in all "helpdesk#dns.org".
I have the following within the Where clause to not include in results:
and aa.AttorneyEmail NOT LIKE ('helpdesk%')
But it still does.
Any help would be appreciated.
Regards,

What you're describing doesn't make much sense. If every row contains the helpdesk address within its AttorneyEmail value (as you say) then a WHERE predicate such as you are trying to use (spelled as #AlexK demonstrates) would exclude all rows. (Also, such a DB structure is pretty ugly.)
In that case, if the point is to strip the helpdesk address from the column value in your results, then you need to do so in the selection list, something like
SELECT REPLACE(aa.AttorneyEmail, 'helpdesk#dns.org', '') AS AttorneyEmail,
...
You may need to adjust that to remove excess delimiters; I can't suggest exactly how because I don't know how you are structuring the values.

Use IIF and LIKE statement in critera column in queries, MS Access

I have homework from Microsoft Access for school and one of the tasks was to make a search form in query, where you type for example 1. grade, 2. grade or 1st year, etc... But the field contains the name of the classes such as IT1, IT2, E1A, E3C, etc... So I could not just make a search form with [Enter Class:] or Like [Enter Class:]&"*" in the criteria column. So I was thinking, that I can use the IIF statement but it doesn't work how I imagined. I think there is a problem with the LIKE statement. I read on forums, that the IIF statement should be used in the field column but I tried the simple examples in the criteria and it worked just fine. So my question is, how I can make a search form, where I type numerous letters with one certain number in it BUT only the number will be read and returned with the same number in classes. Example: I type to search 1. grade and the value will return classes IT1, E1A, E1B, E1C, E1D. This is the line I used in the criteria column:
Like IIf([Enter the grade:]="*1*";"*1*";IIf("*2*";"*2*";IIf("*3*";"*3*";IIf("*4*";"*4*"))))
Just to qualify, I'm beginner in access and databases overall, so there is big possibility, that I'm missing something.
Thank you for help! Cheers!
Assuming input will always start with a number and you want all values containing that number, consider:
WHERE fieldname LIKE "*" & Val([Enter grade]) & "*"
Also assumes values contain only single digit.

How can I group data by matching identical cells in same column then counting instances of a related column?

data output
I am pretty new to Webi and am having an issue creating a variable. I'm trying to check if there is more than 1 email address for each entity legacy account number and if 1 of the contact names contains "Annual Report". So when I flag each entity legacy account number for no email only the ones without a contact name that contains "Annual Report" will be pulled. In the example above only the yellow groups should be called no email. Right now all of them are being pulled into no email. I have tried using if and match as those are what I am most familiar with. Does anyone have any suggestions?
There are number of ways you could do this. I am going to give an example using two variables, but you could easily combine them into one.
Has No Email Var=If(Match(Upper([Contact EmailAddress]); "NOEMAIL*"); 1; 0)
Annual Report Contact Name Var=If(Match(Upper([Contact Name]); "ANNUAL REPORT*"); 1; 0)
Then you would apply a report filter with two components...
Has No Email Var = 1
AND
Annual Report Contact Name Var = 0
Let me explain a few things...
The purpose of the Upper function is the Match function is case sensitive. If you know your email address are always lower case then you could remove that the Upper function and have it match on "noemail*".
It is significant that I only have a asterisk ("*") at the end of the string being sought. That will only find a match where the corresponding column value starts with that string. If you want it to be true whenever the string is found anywhere in the column being searched you would be asterisks on both ends.
You could also put limiting criteria in your query filter. But here is where thing can get confusing. Within the query filter you can choose the Matches pattern operator. However, the wildcard character is different ("%" rather than "*") and you do not put double-quotes around your search text. So you would have some thing like this...
Contact EmailAddress Matches pattern noemail%
AND
Contact Name Different from pattern Annual Report%
I am sure you noticed I didn't convert the search text to uppercase. In the Query Panel Web Intelligence is case-insensitive and would likely follow the case-sensitivity of the database of the source data. All of our databases are case-insensitive so if yours is case-sensitive you may need to play around this this a bit. Or just go with the approach of creating the variables and report filters as I initially laid out.
If you want a wildcard for a single character rather than multiple characters (which is what "*" and "%" will do) you need to use a "?" within your variable definition or a "_" in your query filter.
Hope this helps,

Microsoft Access If statement Query

I'm trying to figure out why my below query is not working.
I have created a calculated field and as part of an IIf() I am looking at doing a LEFT function.
I am hoping to return the First char of the Display Value of a column rather than the Hidden Primary Key.
Just wondering if someone can point me in the right direction?
You can debug this yourself by doing a couple of things. You haven't really provided specific information to what the problem you're facing.
First I would rewrite the query as such to reduce the number of paranthesis and make the intention/logic much clearer, which will also make it easier to debug.
IIf([General Notes] In ("FFA", "Consignment", "CCO", "Hargreaves", "SCRAP"), [General Notes], Left([Supplier_ID],1))
Then start with the following step and identify which field is causing the problem by breaking the query into seperate fields
IIf([General Notes] In ("FFA", "Consignment", "CCO", "Hargreaves", "SCRAP"), [General Notes], "")
Left([Supplier_ID],1)
etc
As for the display value of the column rather than the hidden primary key, [Supplier_ID] sounds awfully like a name that would be given to a key. Perhaps you mean to place something like [Supplier_Name] or [Supplier] etc.

MYSQL search table, bit fields

I have a table with rows and where one field is a bit-value with 7 digits.
Suppose I have a procedure where I want to select all rows where this bit field equals '0101010', this is easily done by select * where .... and so on.
But: how do I do if I want to allow one/multiple digits of the digits to be either 1 Or 0, i.e I want to get all rows where the bitfield has an entry on the form 1001*1* where the * can be either 1 or 0. So, in this case I would like all entries where the bit field is 1001010, 1001011, 1001110 or 1001111.
select * from TABLE where bit_field in (1001010, 1001011, 1001110, 1001111) would probably work in this example, but if I want to use only the string '1001*1*' as input to the procedure, what then?
.
Any help is very appreciated.
Thanks,
Niklas
Edit: I've tried this: select * from table where field like bit'\\\0'; for getting all entries of the form **0, but that didn't work...
Edit2: It turned out it vas a bit-field, not binary... problem still remain though.
Not a direct answer to your question, per se', but an alternative approach. You mentioned that you didn't want to convert to individual columns because of legacy code. If you do want individual columns and the only thing holding you back is the legacy code, consider the following.
You could add columns for the options and use insert/update triggers to populate them OR you could create a view that splits the bits into separate columns. For new development, you can code to the new columns. Over time, as you modify legacy code you can change it to the new approach. When all the "read" legacy code has been changed, the last step is to change the "write" code to use the new columns rather than the bit column and remove the triggers.
I have a SQL Fiddle demonstrating this here. Note that I only included an insert trigger for brevity.

Searching Mysql for similar string

People have different ideas of how to search for the same term.
For example Tri-Valley, Trivalley, Tri Valley (and possibly even incorrect spellings)
Currently that search is done like this
SELECT * FROM `table` WHERE `SchoolDistrict` LIKE '%tri valley%';
Is there an easy way to say 'space dash or no space' without writing out three like statements?
It seems like it could easily be done:
SELECT * FROM `table` WHERE `SchoolDistrict` LIKE '%tri%valley%';
But this only works if the initial input is 'tri-valley' or 'tri valley' If the initial input is 'trivalley' I have no idea where to place the % (theoretically that is, actually, I do, as we are only looking at about a dozen different school districts, but I'm looking to solve the larger problem)
You could consider using SOUNDEX, or SOUNDS LIKE if you have a lot of incorrect spellings. If you've got a lot of rows (or even if you don't), it might be wise to store the output of the SOUNDEX in an additional column.
I'd also recommend -- in the interests of accuracy -- introducing a separate table with an authoritative list of school districts, and run a query to find those which aren't in that list.
MySQL has a function called Sounds like.

An alternative here is to recast the problem from search to select, if possible. Instead of letting your users enter free-form text to choose a school district, if you have a set of school districts generate a dropdown (or set of cascading dropdowns if the list is large, say by county, then by school district) and allow the user to select the appropriate one. Use this both for "searching" and for data entry to eliminate non-canonical entries. Obviously this only works when you can enumerate all of the entries.
Alternatively you could allow the user to choose a starts with or contains type search and simply generate the appropriate SQL ('tri%' or '%tri%') based on the selected search type. If the user understands that the search type is starts with or contains, they will likely adjust their search string until it yields the results they need.
The second statement you posted should do the trick:
SELECT * FROM 'table' WHERE 'SchoolDistrict' LIKE '%tri%valley%';
What you should do before you pass the search term into the select statement is to replace all characters and spaces with the % sign. For example,
SearchTerm = SearchTerm.Replace(" ","%");
